This is not a normal patch/security bulletin that would show up in the patch catalog. You will need to download the hotfix and package it separately, then use a deploy job to roll it out to your servers.

I have an empty Windows Patch Catalog with all filters added that I use for testing purposes. Interestingly, I can find quite a few Hotfix patch binaries when I search for the BULLETIN_ID = MS12-024. But I can find no reference to that KB958476 (QNUMBER contains 958476). I wonder if that particular KB has been superceded by another?

And as Bill said, you can add it to your Depot and deploy that executable any number of ways. I tend to open similar packages (like Hotfixes added to the Depot) to see how BBSA does it and what install/uninstall strings they use for deploying patches.

This might be a bit off, but do you know how I could add this to the depo as a Hotfix with dependency linked to the two service packs and the preceeding hotfix from the original article. I would only install this private fix onto a system that met the prereqs for the hotfix.

I was not able to add it as a hotfix because it was asking for some sort of product key. Maybe, if Microsoft created the "hotfix" as a Hotfix and not just an update (at least that's what it looks like to me), the add as hotfix through BladeLogic would have worked.
